Manny Pacquiao (57-6-2, 38KOs) says his surgically repaired shoulder is 80-90 percent healed, and he expects to resume training in November or December.

He said Monday that he could return to the ring in March, acknowledging that Amir Khan was a possible opponent but adding no decision had been made.

He would welcome a chance to get in the ring with Floyd Mayweather Jr. again.

Mayweather says he is retiring, though Pacquiao recognizes that in boxing, those vows don't always hold up.

"If you ask me, of course, I want a rematch," Pacquiao said. "I heard that he retired already. If he really retired, then there's no rematch. But if not ..."

A congressman in the Philippines, Pacquiao was in Manhattan on Monday to be honored with the Asia Society's Asia Game Changer of the Year Award.
